   AREAS AFFECTED...EASTERN CO
   
   CONCERNING...SEVERE POTENTIAL...WATCH POSSIBLE 
   
   VALID 262040Z - 262245Z
   
   POTENTIAL FOR ISOLATED LARGE HAIL MAY DEVELOP OVER THE NEXT FEW
   HOURS ACROSS THE CO FRONT RANGE. ALTHOUGH QUESTIONS EXIST REGARDING
   THE EXTENT/MAGNITUDE OF THE SEVERE POTENTIAL...WILL MONITOR FOR A
   POSSIBLE SEVERE THUNDERSTORM WATCH.
   
   POST-FRONTAL UPSLOPE REGIME CONTINUES TO EVOLVE OVER EASTERN
   CO...WITH SURFACE DEWPOINTS GRADUALLY RISING AMIDST LOW LEVEL
   SOUTHEASTERLY FLOW...WITH DEWPOINTS WELL INTO THE 40S F ALONG AND
   SOUTH OF THE PALMER DIVIDE AS OF 20Z. PERHAPS AIDED BY A LOW
   AMPLITUDE MID LEVEL IMPULSE...INSOLATION/HEATING AND SOME ADDITIONAL
   INCREASE IN BOUNDARY LAYER MOISTURE WILL BE CONDUCIVE FOR THE
   DEVELOPMENT OF ISOLATED STRONG/SEVERE STORMS NEAR THE I-25 CORRIDOR
   OVER THE NEXT FEW HOURS. ALTHOUGH MID LEVEL WIND SPEEDS ARE MODEST
   /25-30 KT VIA PLATTEVILLE CO PROFILER/...ESPECIALLY WITH SOUTH
   EXTENT...VEERING WIND PROFILES MAY ALLOW FOR SOME SUSTAINED
   STORMS/SUPERCELL STRUCTURES IN AN ENVIRONMENT WITH MLCAPE VALUES OF
   500-750 J/KG. AS STORMS DRIFT EAST-SOUTHEAST THROUGH LATE
   AFTERNOON/EARLY EVENING...IT IS QUESTIONABLE HOW FAR EAST STORMS
   WILL MAINTAIN A SEVERE THREAT ACROSS THE CO PLAINS GIVEN INHIBITION
   IN THE BOUNDARY LAYER.
